I'm missing a part and i can't recall what it is. See the photo below -- it installs on the driver side and that screw you see holds it in place. Also i'm pretty sure the electrical connector you see is supposed to connect and possibly a hose as well but i don't see any hoses hanging aroung that aren't connected. You can tell i just pulled the famous hair dryer -- that my next post in case it's hard to tell, i took the picture standing beside the driver's side front tire. The master cylinder is just above the picture.
